Bug description

If you open the share dialog on windows 11, some controls are too small and cannot be clicked.
For example setting a comment for the recipient of a share has several issues:

The placeholder text appears as a real text that you manually need to delete.
The internal button that you have to use to validate the input is not visible (while present and you can click on it)

Other components have similar issues.

Steps to reproduce

1. Open the share dialog on a file
2. Create a share and test all existing options

Expected behavior

UI is perfect with good sizing
